CVE-2026-11824 - SQLite before 3.53.2 Heap Buffer Overflow via FTS5 fts5ChunkIterate
CVE ID :CVE-2026-11824
Published : June 9, 2026, 8:16 p.m. | 48 minutes ago
Description :SQLite before 3.53.2 contains a heap-based buffer overflow vulnerability in the FTS5 full-text search extension that allows attackers to cause a crash or execute arbitrary code by supplying a crafted database with malicious continuation page metadata specifying a szLeaf value smaller than 4. Attackers can trigger an integer underflow in fts5ChunkIterate() causing an inflated remaining byte count during FTS5 MATCH query processing, leading to a heap buffer overflow of attacker-controlled data in applications compiled with SQLITE_ENABLE_FTS5.
Severity: 8.5 | HIGH
